/CLI=command-language-interpreter

    Specifies the name of an alternate command language interpreter
    (CLI) to override the default CLI listed in the UAF. The CLI
    you specify must be located in SYS$SYSTEM and have the file type
    .EXE.

    If you do not specify a command interpreter by using the /CLI
    qualifier and you do not have a default CLI listed in the UAF,
    the system supplies the qualifier /CLI=DCL by default.
